Pastel Network Partners with to Provide Storage and Protect their NFT Ecosystem against Scams & Fraud

Pastel Network is excited to announce its partnership with (“onXRP”), XRP Ledger’s premier NFT marketplace. onXRP will be integrating Pastel’s Sense and Cascade protocols into its marketplace and modular DeFi ecosystem. This partnership signifies the continued successes of both Pastel and onXRP, and is a massive step forward for the overall NFT ecosystem. It is a testament to the growing need for NFT reliability, security and verifiability, solved via Pastel’s advanced infrastructure.

onXRP is an ecosystem built by the XPUNKs with the purpose of extending web 3.0 to the XRPL. The platform is separated into different modules, including a Decentralized Exchange, an NFT Marketplace and other community-centered services. It also produces and publishes content about the XRPL, NFTs and the crypto industry as a whole to educate the community and lower the barriers of entry for new blockchain entrants.

“Security and authenticity play an increasingly focal role within the entire NFT sphere,” said Kaj Leroy, CEO of “With scams and fakes lurking around every corner, an increasing number of people have fallen victim to ever increasing complex frauds. Up until now, no established marketplace has implemented a tool like this one, and we’re proud to announce that we’re changing the game and putting ourselves ahead of scammers, fakes, and copycats. We’re excited to partner with Pastel Network, and we will work tirelessly to make the integration of their tools a seamless experience for all users and artists on the onXRP NFT marketplace.”

NFT security and storage integrity have become the primary issues affecting organizations across the NFT ecosystem. Scams and frauds are widespread while centralized storage is failing to provide adequate reliability. All layer 1 Blockchains and layer 2 Dapps are experiencing these road blocks and are on the search for solutions. Pastel provides them.

With Pastel’s Sense and Cascade protocols, organizations have the ability to prove authentication and certify the rareness of NFTs while having access to permanent and reliable storage via easily integrable, lightweight open-APIs.

How does the integration work?

Pastel Network has not only worked relentlessly to develop incredible infrastructure for the NFT ecosystem, but to also deliver it to network partners in a lightweight, seamless manner. Partners of the Pastel Network such as onXRP and along with other native blockchains or dApps are granted an API Key and Token, which is used to interact with a Pastel Network API Server. The API Key and Token makes requests to the Pastel Network API Server, running a Full Pastel Node signed by the onXRP PastelID.

During NFT minting on onXRP, secure and authenticated (OAuth2) REST API calls are made via an API Server that passes the hash of the candidate NFT to Pastel Network. The return responses — 1) a JSON file with the relative rareness score in the case of Sense and 2) the SHA3–256 hash for the JSON file stored in Kademlia which itself contains the SHA3–256 hashes of the set of redundant copies of the JSON files in Kademlia — are signed by 3 randomly selected SuperNodes operating on the Pastel Network. Smart tickets write and store the outputs to the Pastel blockchain, which is returned to onXRP and included as additional Response fields in their own NFT standard.

Sense is near-duplicate NFT detection protocol on the Pastel Network, built to assess the relative rareness of a given NFT. Sense recognizes the most subtle similarities between two digital collectibles, even if one has been transformed. The protocol goes beyond the standard “digital fingerprint” approach to establishing the rareness of an NFT, and actually looks at the rareness of the pixel patterns in data. While digital fingerprints do allow users to verify that an NFT was created by a particular creator, this is a fairly weak form of rareness. Sense solves this problem by assigning a ‘Relative Rareness Score’ to quantify how rare an NFT is relative to all NFTs in the underlying dataset.

Sense leverages a number of pre-trained deep learning models to transform each NFT into a fixed list of over 10,000 numbers (the ‘NFT fingerprint vector’). It then assesses the correlation between a given fingerprint and the database of all existing fingerprints on Pastel and onXRP’s platform, other NFT marketplaces (e.g., Rarible, OpenSea), and open databases on the entire internet (e.g., Google) and outputs a relative rareness score — a number between 0% (i.e., the NFT is identical to a previously registered NFT) to 100% (i.e., the NFT is completely unique). Sense “sees through” superficial changes in the same way as a human eye, and, like a human, can recognize even the most subtle change in an NFT.

Cascade is a distributed storage protocol purpose-built for NFT metadata in a fully redundant, decentralized, and permanent manner. Pastel is the first NFT platform to have its own completely integrated, decentralized storage layer. Cascade is based on the advanced technologies of RaptorQ and Kademlia and ensures that users only pay once to store their data forever.

By leveraging the RaptorQ fountain code algorithm, Cascade begins by breaking each asset into a series of redundant chunks. Every chunk contains certain random fragments of the combined file which is distributed redundantly across participating SuperNodes running on the network. Two parameters control how the data is encoded into chunks: 1) size of each chunk and 2) desired redundancy factor. The sets of chunks are then randomly distributed across network nodes using Kademlia. No complex or centralized system for deciding which node is responsible for which chunk, no iteration through SuperNodes to find one with the relevant chunk, and no complicated logic for handling chunk re-allocation when SuperNodes enter and leave the network.

These first-of-their-kind protocols combat the most challenging of issues that every organization and individual is experiencing across the NFT ecosystem. onXRP clearly saw the need for next-generation solutions to help support its network and platforms. This partnership with onXRP is a prime showcase for what Pastel can offer to the entire space.

About Pastel Network

Pastel is the world’s preeminent protocol standard for NFT technology. Pastel also allows for the development of third-party applications to sit on top of its Network, enabling developers to enjoy the scalable registration features, storage processes, and security of the broader ecosystem. Lightweight protocols such as Sense — which was built to assess the relative rareness of a given NFT against near-duplicate metadata — and Cascade — which conducts permanent, distributed storage of underlying NFT data — can be integrated across any native L1 blockchains or L2 marketplaces.

Pastel is an entirely native blockchain supported by SuperNodes, which provides computational resources to the network to support asset registration, distribution, and permanent storage. Pastel is managed by world-class developers, cryptographers, and technologists, supported alongside an experienced and extensive network of marketers, influencers, and third-party agencies. Pastel is backed by key stakeholders including Innovating Capital, a prominent venture fund.
